Cost per warranted kWh 1 cycle per day
If the solar battery is cycled once per day, this is how much each warranted kilowatt-hour of stored electricity will cost. Once an individual product’s price per kilowatt-hour drops below 10 cents, battery storage is likely to be a worthwhile investment for a large number of households. This graph scrolls left to right – try it to see the really expensive units…
Cost per Total Warranted kWh (1 cycle per day)
We update this comparison table frequently as more business and home energy storage systems become available, and specs and prices of existing solar batteries change.
Please note system pricing is our best estimate of retail prices inclusive of GST, unless specifically noted otherwise. But it is only an estimated cost.
TIP: If you’re not 100% certain what a kWh is, or don’t understand the difference between a kW (kilowatt – a measure of power) and a kWh (kilowatt-hour – a measure of energy), read this: The Difference Between Power And Energy. It’s important to be clear on the difference between the two when researching battery storage or anything solar-related.
Solar Battery Storage Usable Capacity (kWh)
Usable capacity is the energy stored in a solar battery system that can actually be used. In most cases this is less than the nominal storage capacity figure provided.
For example, the Enphase AC battery has a total storage capacity of 1.2kWh. But as only 95% of that stored energy can be discharged (aka a 95% Depth Of Discharge) the battery’s usable storage capacity is really 1.1kWh.
Solar Battery Power (kW)
A solar battery’s power rating is how fast it can be charged or discharged.
For example, an Enphase AC battery is a low power solar battery storage system (also known as an ‘energy’ battery) because it takes 4 hours and 23 minutes to discharge all its usable energy, while the BMZ ESS is considered a high power battery because it can discharge all its usable energy in under 40 minutes.
A high power home battery system isn’t necessarily more desirable than a low power battery – your household’s unique energy usage needs will determine how much power you will require from a solar battery and the best energy storage solution for you.
Most home solar batteries are lithium-ion based chemistry, but there are variety of different lithium-ion chemistries. The type widely considered the safest is lithium iron phosphate (LiFePO4).
But regardless of the chemistry, a solar battery is only as safe as the safety mechanisms built into it and the care taken in manufacturing; so chemistry type is just one aspect that should be considered when making a purchase decision in terms of safety.
It’s worth noting there have been very few fires in Australia involving new-generation home solar batteries to date, thanks to strict installation standards.
All In One Unit
This means the system includes batteries, a battery management system (BMS) and an inverter. The Sunverge SIS is one example of an all-in-one home energy storage system.
If a battery management system and/or inverter have to be purchased separately, this will add to the total cost of the system.
Warranty Document Supplied?
Links to a warranty document if it is available. Don’t buy a solar battery system until you have read the latest version of its warranty document sourced direct from the supplier. They change often and the linked versions we provide above may not be the most current documents available.
Total Warranted kWh (1 Cycle Per Day)
If you only discharge the battery once per day (most likely for larger solar batteries in residential installation situations), then the warranty period may expire well before the warranted kWh level has been reached.
The number of kilowatt-hours (kWh) a home battery system can discharge per day is multiplied by the number of days in the warranty period in order to generate the total warranted kWh figures.
Cost Per Warranted kWh (1 Cycle Per Day)
This is the solar battery price (excluding installation) divided by ‘Warranted kWh (1 cycle per day)’. If you discharge the battery approximately once per day, this number indicates what home energy storage system may be the most cost-effective in your circumstances.
A Note On Battery Warranties
Some solar batteries in the table have different warranties for components within the unit. For example, some “all in one” home battery storage systems warrant the battery cells for 10 years, but the internal inverter only has a warranty of 5 years.
We use the ‘weakest link’ warranted figure (so in the above example, 5 years instead of 10 years) when calculating the cost per warranted kWh.
Disclaimer: Although we strive to review the information in this comparison table regularly to keep it up to date and as accurate as possible, mistakes may be made and prices and other figures/specifications can change very quickly given the solar battery storage scene is quickly evolving.
Check with battery manufacturers before making any solar storage purchase decisions based on information provided in this table.
